DATACOMP_SUFFIX keyword

Use the DATACOMP_SUFFIX keyword to specify the suffix portion of the VSAM data component name.

DATACOMP_SUFFIX is an optional keyword for the JCLPARM subcommand.

The suffix you specify for the DATACOMP_SUFFIX keyword is used to determine the data component name for shadow ADSs and UICs. The data component name is cluster_name + suffix. For shadow ADSs, the cluster name is determined by the DSNMASK_SHADOW keyword. For UICs, the cluster name is determined by the DSNMASK_UIC keyword.

For restructured ADSs:
  • If the DATA parameter is specified in the IDCAMS control statement, the data component name must be cluster_name + suffix and the suffix portion must match the DATACOMP_SUFFIX keyword value.
  • If the DATA parameter is not specified in the IDCAMS control statement, if DATACOMP_SUFFIX=DATA, the cluster name of the restructured ADSs must be less than or equal to 38 characters. If DATACOMP_SUFFIX=D, the cluster name for the restructured ADS must be 39 to 42 characters.
For more information, see VSAM cluster names for area data sets (ADSs) and user image copies (UICs).
